Description

Plug interface, plug element and micro travel vehicle
Technical Field
The invention relates to a plug interface, a plug element and a micro travel vehicle.
Background
Micro travel vehicles with plug interfaces, such as booster bicycles, electric scooters or recumbent bicycles, are known from the prior art. These plug interfaces are in contact with the corresponding counterparts. For fastening the counterpart, the plug interface has a mechanical fastening element, for example a USB interface. This is disadvantageous in view of the limited available installation space. Furthermore, it is difficult to protect the plug interface from dust and moisture. In the event of a fall, the mechanical fastening element is subject to the risk of damage.
An electric bicycle with an energy storage device is known from JP 2017103942A. The mobile terminal device is shown as being coupled to the energy storage device via a USB interface.
Disclosure of Invention
The object of the invention is to avoid the disadvantages mentioned at the outset. This object is achieved by a plug interface according to claim 1, a plug element according to claim 5 and a micro-travel vehicle according to claim 8. Preferred developments are contained in the dependent claims and result from the following description.
The plug interface for the micro-travel vehicle is designed for releasable connection with the first connection region of the plug element and is integrated into the frame of the micro-travel vehicle. The plug interface is provided with a connection element having at least one magnetic means configured for forming a magnetic attraction force with a corresponding magnetic means of the first connection region of the plug element. The plug interface is designed for energy efficient connection with an energy storage device of the micro-travel vehicle. The connection element of the plug interface has at least one contact surface, wherein the at least one contact surface is designed for contact with at least one spring-loaded pin of the plug element, wherein an energy-efficient connection is established. The input voltage of the plug interface is up to 12V. The output voltage that can be supplied to the plug element via the plug interface is up to 12V.
A micro-travel vehicle is defined as a vehicle with (auxiliary) electric motors but which can also be operated by muscle force. The driving of the micro-travel vehicle is achieved by means of electric motors only, i.e. by muscle forces (e.g. pedal-driven and/or hand-driven and/or foot-driven), by electric motors in combination with muscle force driving or by muscle force driving only at different times. The electric motor supports the driver when driven by the electric motor in combination with the muscle force drive. The micro travel vehicles are suitable for private traffic. For example, the micro-travel vehicle may be shaped as an electric bicycle, (high speed) booster bicycle, recumbent bicycle, electric scooter, unicycle or other suitable vehicle.
The plug interface is configured for releasable connection with the first connection region of the plug element. The connection may be repeatedly opened and closed. The connection between the plug interface and the plug element is established by magnetic attraction without closing the mechanical connection. In particular, no embedding of the pins into the receptacles for the pins takes place. For this purpose, the plug interface has a connection element which in turn has at least one magnetic device. The magnetic component can be formed either in one piece or from a plurality of sub-elements. Preferably, the magnetic means is configured such that it has at least one recess into which the contact surface can be accommodated. The magnetic device may be a magnet or a ferromagnetic device. At least one of the two magnetic means of the plug interface and the plug element is configured as a magnet, while the other means may be a magnet or a ferromagnetic means.
The plug element is fixed to the plug interface in the contact state due to the magnetic attraction between the magnetic means. In order to release the plug element from the plug interface, only the magnetic attraction force has to be overcome. Due to the magnetic means, the mechanical means for fixing the plug element are discarded. Thus, the disadvantages associated with the mechanical fastening devices described above can be avoided.
The plug interface is configured for integration into a frame of a micro-travel vehicle. That is, the frame has a receiving portion into which the plug interface is inserted. According to a further development, at least a part of the plug interface is thus engaged with the frame. The housing of the plug interface is then fastened to the frame, preferably screwed to the frame. Preferably, the fixing of the plug interface in the frame is rigid, i.e. there is no possibility of relative movement between the plug interface and the frame. If the plug interface is integrated into the frame, the plane is shaped such that the plug interface protrudes beyond the frame only to a very small extent. Preferably, the plug interface does not protrude beyond the frame.
The plug interface is designed for energy efficient connection with an energy storage device of the micro-travel vehicle. Energy-efficient means that the plug interface can be supplied with energy by means of an energy storage device. The input voltage of the plug interface provided to the plug interface by the energy storage device is up to 12V. That is, energy is directed from the energy storage device to the plug interface. These and further description of the numerical values in the description should be noted that these values are always understood with the usual tolerances for the technical application field.
The connection element of the plug interface has at least one contact surface, wherein the at least one contact surface is designed for contact with at least one spring-loaded pin of the plug element, wherein an energy-efficient connection is established. At least one of the contact surfaces is shaped as a flat surface. The flat surface is preferably rigid, i.e. no possibility of a relative movement into the plug interface is established. At least one contact surface is formed from an electrically conductive material. If the at least one contact surface is contacted by means of at least one spring-loaded pin of the plug element, an electrical current and/or voltage can be transmitted to the plug element via the at least one contact surface. Such a connection for energy transmission is called an energy efficient connection. In this contact, the pin is not embedded in the contact surface, but only touches the contact surface.
When the plug element is connected to the plug interface, the output voltage provided by the plug interface to the plug element may be up to 12V. The plug interface may have a converter that may convert the voltage such that the output voltage of the plug interface is lower than the input voltage of the plug interface. For example, the output voltage of the plug interface may be 5V or 9V.
The advantage of the plug interface and the system of plug interfaces and plug elements is that a simple re-operation of the plug interface can be achieved even in the event of dirt. Dirt can be wiped off in a simple manner. No dirt that would prevent contact by means of the plug element can enter the plug interface.
According to a further embodiment, the connection element of the plug interface has at least three, in particular four contact surfaces, wherein each contact surface is designed for contact with a corresponding spring-loaded pin of the plug element, wherein an energy-efficient connection is established. At least two of the at least three contact surfaces are used here only for energy transmission. In this case, one contact surface can be designed as a ground. For example, the contact surfaces may be arranged in series with each other. Of course, any other arrangement is also possible. All contact surfaces lie in one plane. Of course, the connection element of the plug interface may have more than four contact surfaces.
The plug elements forming the counterpart of the plug interface have as many pins as there are contact surfaces of the plug interface. In other words, one pin is provided for each contact surface. The plug interface and the plug element are thus configured to mate with one another. Contact of the plug interface with plug elements provided with a different number of pins than the number of contact surfaces is not possible.
The magnetic force acting between the magnetic means of the plug interface and the magnetic means of the plug element is determined such that it overcomes the sum of all spring forces acting between the respective contact surfaces and the corresponding contact pins.
The contact surface is configured such that it does not short out when in contact with water. Bridging by unsuitable structural elements, for example by clips or wires, is also not possible. The contact surface is thus designed such that it does not short-circuit. Thereby, greater safety is ensured for the vehicle user.
According to a further embodiment, at least one of the contact surfaces is additionally shaped as a data transmission device. Thus, data can be encoded in particular in the transmitted electrical signal. For example, it is diagnostic data. The plug interface is at least partially modified to a diagnostic interface. The diagnostic device can be connected as an external device to the micro-travel vehicle via the diagnostic interface by means of the plug element. The diagnostic device enables access to diagnostic data of electrical or electronic components of the micro-travel vehicle.
According to a further embodiment, the plug element can be provided with a maximum charging power of up to 20W by the connection element of the plug interface. The charging power may be provided via the plug element to, for example, a mobile terminal device, such as a smart phone, a tablet, a diagnostic device, a smart watch, etc. In other words, the mobile terminal device, or rather the energy storage device of the mobile terminal device, can be charged by the energy storage device of the micro-travel vehicle via the plug element.
The plug element for use with the plug interface already described and with the mobile terminal device has magnetic means. The plug element is designed for releasable connection with at least one magnetic element of the plug interface by means of a magnetic element of the plug element arranged on a first connection region thereof. Where a magnetic attractive force is formed. The plug element has a second connection region which is designed for releasable connection with an interface of the mobile terminal device. The plug element additionally has at least one spring-loaded pin on its first connection region, which pin is designed for contact with a corresponding contact surface of the plug interface. An energy-efficient connection is established between at least one pin and a corresponding contact surface of the plug interface.
The magnetic means of the plug element can be formed either in one piece or from a plurality of sub-elements. Preferably, the magnetic means is configured such that it has at least one recess into which the pin can be accommodated. The magnetic device may be a magnet or a ferromagnetic device. At least one of the two magnetic means of the plug interface and the plug element is configured as a magnet, while the other means may be a magnet or a ferromagnetic means.
The pins are contact pins with springs that pre-load the pins. Thus, the pins are loaded with a spring force that resists movement of the pins. When contacting, the pin is clamped against the contact surface of the plug interface by the spring force. For example, such pins may be referred to as Pogo pins. At least one of the pins is configured to be electrically conductive. The transmission of energy to the plug element can be achieved if at least one pin contacts a corresponding contact surface of the plug interface. Thus, when the plug interface and the plug element are used in the micro-travel vehicle, energy from the energy storage device of the micro-travel vehicle may be directed to the plug element via the plug interface.
The first connection region may have more than one pin. The first connection region may have, in particular, two pins, three pins, four pins or more pins. The number of pins depends on the number of corresponding contact surfaces of the plug interface. The first connection region of the plug element is connected to the second connection region of the plug element by means of a cable.
The plug element has the advantage that a non-embedded contact of the corresponding contact surfaces is possible due to the pins. In the event of an accident in the micro-travel vehicle, the plug element is released from the plug interface without damage. Damage to the plug interface and/or the plug element is thereby prevented.
According to a modified embodiment, the second connection area is shaped as a USB interface or a lightning interface. The second connection area may be connected with a mobile terminal device, such as a smart watch, a tablet computer, a diagnostic device, a smart phone, or the like. The USB interface may be shaped, for example, as USB-A, USB-B, USB-C, mini-USB, micro-USB, or the like. In addition to the energy transmission, data transmission can also take place if necessary via the second connection region
If the mobile terminal device is configured as a diagnostic device, then the diagnostic data of the electrical or electronic components of the micro-travel vehicle can be accessed when the plug element is used with the micro-travel vehicle and one of the contact surfaces of the plug interface is additionally configured as a data transmission device.
Through the second connection region of the plug element, an output voltage of up to 12V can be provided for the mobile terminal device. For example, an output voltage of 5V or 9V may be provided. For example, a charging power of up to 20W may be provided in order to charge the energy store of the mobile terminal device.
The micro-travel vehicle has an energy storage device. The micro-travel vehicle has a plug interface as already described. The plug interface is integrated into the frame of the micro-travel vehicle, wherein the plug interface is energy-effectively connected with the energy storage device of the micro-travel vehicle. This has also been described.
